No Signs of Aliens Yet, But This Mysterious Star Continues to Baffle Astronomers

A new report indicates that Tabby’s Star is dramatically decreasing in brightness, raising more questions about the mechanism behind the fluctuations. A STRANGE STAR Last fall, an unassuming star called KIC 8462852 became a hot topic among astronomers and astronomy fans after the planet-hunting Kepler telescope showed unusual light fluctuations in the area. At the […]

ESO Confirms: Earth-Sized Planet Found Around the Closest Star to Earth, Proxima Centauri

A new planet that bears striking similarities to our own planet prompts remarkable inroad into the study of space. This also brings a new area to search for the possibility of extraterrestrial life. THE PALE RED DOT CAMPAIGN Back in 2013, the first signs of a planet over four light-years from our solar system were […]

A planet with no home

NASA just discovered a new lonely planet with no host star. To make sense of space, we tend to group things up. For example, our planet is a part of the Solar System, which is part of the Milky Way galaxy, which sits in the Laniakea region of the Universe, and so on. These groups […]

Cassini Solstice Mission: Saturn’s Rings: Less than Meets the Eye?

It seems intuitive that an opaque material should contain more stuff than a more translucent substance. For example, muddier water has more suspended particles of dirt in it than clearer water. Likewise, you might think that, in the rings of Saturn, more opaque areas contain a greater concentration of material than places where the rings seem more transparent.

But this intuition does not always apply, according to a recent study of the rings using data from NASA’s Cassini mission. In their analysis, scientists found surprisingly little correlation between how dense a ring might appear to be — in terms of its opacity and reflectiveness — and the amount of material it contains.
